receiving, by the first electronic device, information about one or more users with whom a user of the first electronic device establishes a human relationship;

identifying, by the first electronic device, a user selected based on an input of the user of the first electronic device among the one or more users;

sending, by the first electronic device, said one of the first information and the second information and third information about the identified user to the server;

storing, in the server, said one of the first information and the second information in connection with an identifier of the user of the first electronic device and an identifier of the identified user;

monitoring, by the server, a location of at least one of the first electronic device and a second electronic device of the identified user based on the first and second information stored in a database; and

sending, by the server, a notification message to one of the first electronic device or the second electronic device through the communication session, when the other one of the first electronic device or the second electronic device deviates from the location range at a time corresponding to the time range.

8. The method of claim 7 , wherein:

the user interface includes a map on a screen of the first electronic device; and

the generating generates the first information based on a range set on the map according to an input of the user of the first electronic device on the map.

9. The method of claim 8 , wherein:

the screen of the first electronic device is a touch screen; and

the generating the first information comprises,

recognizing the range set through a touch gesture of the user of the first electronic device on the touch screen.

10. The method of claim 7 , wherein:

the user interface enables the user of the first electronic device to set a source and a destination; and

the generating generates the first information based on at least one route between the source and the destination.

11. The method of claim 7 , wherein:

the user interface enables the user of the first electronic device to select a route for each vehicle; and

the generating generates the first information based on the route of each vehicle selected through the user interface.

12. The method of claim 7 , wherein:

the location range includes a first location range and a second location range; and

the sending the notification message comprises sending the notification message to the one of the first electronic device and the second electronic device if it is determined that the other one of the first electronic device or the second electronic device, which deviates from the first location range at a time corresponding to the time range, does not move to the second location range.

13. A non-transitory computer-readable recording medium storing computer-readable instructions, which when executed by a processor, cause the processor to perform the method of claim 7 .

14. A method comprising:

establishing, by a first electronic device, a communication session for communicating a message with one or more other electronic devices;

providing, by the first electronic device, a user interface for receiving a time range and a location range;

generating, by the first electronic device, first information about the time range and second first information about the location range based on information input through the user interface;

receiving, by the first electronic device, information about one or more users with whom a user of the first electronic device establishes a human relationship;

identifying, by the first electronic device, a user selected based on an input of the user of the first electronic device among the one or more users;

sending, by the first electronic device, the first information, the second information, and second third information about the identified user to a server;

storing, in the server, the first and second information in connection with an identifier of the user of the first electronic device and an identifier of the identified user;

monitoring, by the server, a location of at least one of the first electronic device and a second electronic device of the identified user based on the first and second information stored in a database; and

sending, by the server, a notification message to one of the first electronic device or the second electronic device through the communication session, when the other one of the first electronic device or the second electronic device deviates from the location range at a time corresponding to the time range.
